7 Using the 780C Test Instrument Installer Test Utility
This section provides procedures for diagnosing HDMI and HDBaseT networks using the automated Installer
Test.
The features and functions described in this section are included as a standard feature. The
Installer Test enables you to quickly and simply identify common interoperability problems. The Installer Test
enables you to conduct step by step diagnostics toward the source
—upstream (
Source Test) , toward the
sink
—downstream (
Sink Test) , or in a looped configuration around a repeater device ( Repeater Test ). You
can also conduct both and upstream and a downstream diagnostic test at the same time using the Link Test.
Table 7-1 below describes what items are tested with each test in the Installer Test.
